VAPOR-GENERATOR.

Specification of Letters Patent, Application filed July 30, 1909.

Patented Dec. 9, 1913. Serial No. 510,438.

To all whom it may concern.

Be it known that I, EDWARD Snrrz, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Vapor-Generators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in vapor lamps and vapor lamp systems and pertains particularly to a vapor generator for the same.

It is customary to provide for generators of this class a filling or packing of asbestos, metal filings, gravel stones or other noncombustible material kept highly heated whereby the hydrocarbon fluid which spreads over and through it and thus contacts with a large heating surface will rapidly vaporize. This method, however, is more or less troublesome in that the heavy oils left after vaporization takes place clog the packing and interfere with the proper operation of the lamps and it is necessary from time to time to remove and thoroughly clean the parts.

It is the purpose of this invention therefore to substitute for the older form of generator one of a difi erent type and one that will give no trouble of this kind and at the same time will be thoroughly etlicient.

The invention includes a hydrocarbon gas generator wherein a liquid hydrocarbon, such for instance, as gasolene, is supplied to a vaporizing device having a heating burner, or its equivalent, by which the said vaporizing device is heated, and a conduit for carrying into and directly depositing upon a superheated body the fluid to be vaporized. The fluid is not injected into the generator from a point outside it but is carried into it and deposited after being initially heated, since the conduit carrying the fluid derives heat from the heated generator.

In order that the invention may be clearly understood I have provided the accompanying drawing in which Figure l is a vertical sectional elevation of the generator and its parts. Fig. 2 is a longitudinal section of a part of the generator shown in Fig. 1 but on a much larger scale. Fig. 3 is another form of the same part. Fig. 4 is a horizontal section of a fitting on line a a Fig. 1. Fig. 5 is a vertical transverse section of a portion of an inlet valve shown in Fig. 1.

A indicates a conduit leading to a lamp or a series of them into which vapor is discharged lrom the generating portion of the apparatus about to be described, and B is a branch pipe connected into the conduit A and terminating in a tubular fitting C which has an enlargement D to be more fully described later. From said fitting depends a conduit E provided at F with a regulating valve, said conduit terminating in an up turned extension G provided with a burner H in a manner common to many devices of this character. Above said burner is a vessel J which may be termed a retort and which is preferably a hollow casting from opposite sides of which project hollow extensions K L, the former connecting into or forming a part of a pipe M provided with a discharge orifice N controlled by a needle N and through which vapor is supplied to the conduit A of the lamp system, there being any usual mixing tube 0 interposed bctween the orifice and said conduit to which however I attach no claim to novelty herein. The vessel or retort J is closed at its top except for a threaded aperture P which receives a threaded plug Q; and through this aperture the interior of said vessel may be reached. The hollow exten* sion L already referred to is preferably provided with an enlargement L having a flat face L to abut against an end wall of the fitting O above mentioned. This wall and the opposite one each has an opening R therein in line with the bore of the extension L to receive a pipe S provided with a screw threaded part at T to engage the enlargement L. The pipe S also has a threaded portion at U to receive a nut V which serves to firmly clamp the fitting C against the said enlargement L. The extreme end of the thread-portion U receives one end of a tubular member W of a valve 2 which con1- ing into the pipe S and S through said space prises said member W and a tubular portion 3 at right angles thereto all being cast as a single part as shown in section in Fig. 5. The opposite end of the portion 7 is provided with screw-threads to receive the threaded portion of a needle 5 which extends into the tube S, and a cap 6 together with a suitable packing 7 constitutes a stutting box to prevent leakage around said needle.

In the wall of the part V is an aperture 8 which communicates with the bore of the portion 3 described the latter having an interior wall 9 provided with an aperture 10 closed by a needle 11 which is provided with screw threads and engages the threads of an aperture 12 in an interior wall 13 of said portion 3, a cap 14 and a packing 15 being provided to prevent leakage around the needle. A pipe for carrying hydrocarbon fiuid is suitably attached to one end of the portion 3 and is indicated by the numeral 16. The pipe S which forms a part of the present invention terminates within the vessel or retort J preferably in the top of the latter near its center. Its extremity within the vessel terminates in a thick wall inclicated by S in which a notch S is created leaving a thin wall adjacent to the bore of the tube which has a jet orifice 17 controlled by the needle 5 hereinbefore described, Fig. 3 showing a tube S for the purpose provided with an aperture S but without a needle. However, since the jet orifice is entirely inclosed in the vessel J it cannot be cleared of deposits as can be done with orifices in other types of this class of device, in the present instance the needle 5 is preferably arranged to enter and directly control the orifice and it serves to keep said ori fice perfectly "tree and open. The hydrocarbon fiuid in the pipe 16 passes the needle 11 into the portion 3 and enters the portion W through the aperture 8 thence passout through the orifice 17 into the vessel or retort J the latter containing preferably, though not of necessity, a filling of asbestos or other suitable material J. The vessel J being heated by the burner H vaporizes the fluid introduced into it and this is carried to the lamp system through the conduit A andto the said burner H through the conduit B. An annular space surrounds the pipe S within the tubular extension L and the heatfrom the metal of the latter serves to heat the pipe sufiiciently to raise the temperature of the fluid in the tube S so that being already hot it will, when discharged from the orifice 17, be instantly vaporized. A depending limb S of the wall S of the pipe S created by the notch S serves to deflect the hydrocarbon fluid downward into the vessel J. In addition to heating the pipe S through the medium of the heat within the space of the extension L the ieated vapor in passing through the pipe B to the burner H impinges upon the said tube within the tubular fitting C in passing around said pipe and this also aids in raising the temperature of the fluid.

An advantage arises in constructing the fitting G as shown in Figs. 1 and l in that the pipe S can be placed centrally of the bore of the extension L by means of the enlargement L and the latter and the nut V and its parts may all be firmly clamped together in proper position and can be quickly detached when making repairs and the parts can all lie in one plane and thus present a neater appearance than would otherwise be the case. The form of thevalve 2 permits the needles 5 and 11 to extend past one another at right angles and the passages to communicate with one another through the orifice 8, one of the valves governing the flow of fluid from the pipe 16 and the other governing the discharge orifice 17.

My structure precludes the necessity of employing filling materials within pipes that carry the hydrocarbon by depositing said hydrocarbon directly into a large highly heated member wherein it is quickly and thoroughly vaporized the parts requiring, therefore, little or no attention.

Having thus described my invention, I claim.
